Button-combo to access the emulator menu still sends even the second button input to the game

[NintendoManiac64]

The button-combo method of access the emulator menu, such as Start and X, + and -, 1 and 2, etc. results in an issue where both of the actual inputs are still sent to the game itself. This issue however is present even in Not64 and WiiSXRX, so it's extremely possible that it's simply inherent to the front-end.

This issue most greatly impacts the GameCube controller configuration since it's the only controller config to not have the option to access the emulator menu with only a single button in the way that wiimote by itself, wiimote + nunchuck, and classic controller does (whereby you can workaround the issue by setting the emulator menu button to "Home" and then simply not mapping any of the N64 buttons to "Home")
